MANUFACTURE OF BUTTONS.

SPECIFICATION forming part of Letters Patent No. 317,226, dated May 5, 1885.

Application filed February 16, 1885.

T at whom it may concern.-

Be it known that I, ALFRED J. SHIPLEY, of Waterbury, in the county of New Haven and State of Connecticut, have invented a new Improvement in the Manufacture of Suspender- Buttons; and I do hereby declare the following, when taken in connection with accompanying drawings andthe letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a face view of the button; Fig. 2, the back, showing the bar as introduced; Fig.

1 3, a section through the back, showing the bar therein with the flange turned inward; Fig. 4, a central section through the two parts united, showing the bar in place.

This invention relates to an improvement in the manufacture of that class of buttons commonly called suspenderbuttons, and in which a central opening is formed through the button, with a bar across that opening as a means for sewing the button to the suspender,

2 5 such buttons being known as bar buttons.

Various devices have been resorted to to secure the bar so as to retain it in its central position across the opening. This has been done by bending the bar in various shapes, so as to give so long abearing within the button as to prevent the displacement of the bar. The liability of the bar to get out of place is only during the process of manufacture-that is, in the assembling of the partsit being 5 difficult to retain the bar in its central position in one part while the other part is placed upon it and introduced into the dies for closing, the bar being liable to displacement in this operation, and so that when the button comes from the dies the bar will be often so far out of place as to make the button unsalable.

The object of my invention is to temporarily secure the bar so that the bar may be simply a straight piece of wire without bending or shaping; and it consists in placing the bar into the one part, the edge of the part turned inward sufficiently to hold the bar in place during the operation of closing, as more 50 fully hereinafter described.

In illustrating the button I show it as formed from a back, a, and a front, b, of usual shape,

(No model.)

the back being constructed of cup shape-that is, with an upwardly-projecting flange, cl, and the front with a downwardly-projecting flange, 5 5 e, which is set over the back and closed thereon, as seen in Fig. 4. In the usual construction the flange of the back is flaring, as indicated in brokenlines, Fig. 3, and so that the back simply closes over it.

In my invention I cut the barf of a length corresponding to the internal diameter of the back, and lay it into the back, as indicated in Fig. 3, and then in suitable dies strike the back to turn the edge of the flange inward, and so as to overhang the bar, therebypreventing the displacement of the bar. Thus assembled, the front is applied and the parts struck in the usual manner to unite them, as seen in Fig. 4. Under this construction there is no liability of the displacement of the bar in assembling. The backs and bar may be united in mass, and the front applied at any" time, the operator not being obliged to assemble the three parts and keep them in their proper relation while introducing to the die, there being no difficulty in assembling two parts, as the back and bar; but three partsas the back, bar, and front-assembled and held for introduction to the dies offers a considerable difficulty in the process of manufacture. In some cases the back is made to inclose the front. In such construction the bar is applied to the front. In this construction Fig. 4 represents the button inverted.

It will be understood that the front and back are constructed with the usual central opening, it.

I claim- That improvement in the manufacture of bar buttons which consists in striking up a front and back disk, each having a central perforation and aperipheral flange, introducing into one disk centrally across the perforations a straight bar of proper length to fit the 5 inner walls of the flange, bending said flange down sufliciently to hold said bar in place, and subsequently inclosing the edge of said disks within the flange of the other disk, substantially as set forth.
